Analah means fire. He in the form of fire sustains life. A minimum amount of heat is necessary for life to continue be it in the human body or be it in the Earth itself. This warmth of life in the world around and in every organism, without which we cannot think of life is the Supreme Lord Vishnu. He is our very Self, the very Vital factor in the Praana. He is hugging us all the time in the warmth of compassion and love like a mother hugging her children. We fail to recognize that hug and look out for something which will be soothing to us. Even this ignorance is all burnt in the fire of knowledge, when we start counting our innumerable blessings and hugs we receive from Him every moment of our life.
